在methods:中写：

	//检查手机号
	isCellPhone(val) {
	      if (!/^1(3|4|5|6|7|8)\d{9}$/.test(val)) {
	        return false;
	      } else {
	        return true;
	      }
	    },

在template中

	<el-form :model="formedit" ref="ruleForms" :rules="ruleEdit" label-position="left">
    <el-form-item label="姓名" :label-width="formLabelWidth" prop="newName">
      <el-input v-model="formedit.newName" autocomplete="off"></el-input>
    </el-form-item>
    <el-form-item label="手机号" :label-width="formLabelWidth" >
      <el-input v-model="formedit.newPhone" autocomplete="off" disabled></el-input>
    </el-form-item>
    <el-form-item label="权限" :label-width="formLabelWidth" prop="newRoleId">
      <el-select v-model="formedit.newRoleId" placeholder="请选择权限">
        <el-option label="超级管理员" :value="1"></el-option>
        <el-option label="管理员" :value="2"></el-option>
      </el-select>
    </el-form-item>
  </el-form>

需要验证手机写的是 element框架中prop="phone"验证规则

	<el-form-item label="手机号" prop="phone">
      <el-input v-model="formAdd.phone" autocomplete="off"></el-input>
    </el-form-item>

data中

		 data() {
		    var checkphone = (rule, value, callback) => {
		      // let phoneReg = /(^1[3|4|5|6|7|8|9]\d{9}$)|(^09\d{8}$)/;
		      if (value == "") {
		        callback(new Error("请输入手机号"));
		      } else if (!this.isCellPhone(value)) {//引入methods中封装的检查手机格式的方法
		        callback(new Error("请输入正确的手机号!"));
		      } else {
		        callback();
		      }
		    };
		    return {
		      rules: {
		        userName: [{ required: true, message: "请输入姓名", trigger: "blur" }],
		        phone: [{ required: true, validator: checkphone, trigger: "blur" }],//validator: checkphone是验证手机的引入checkphone函数    
		        roleId: [{ required: true, message: "请选择权限", trigger: "change" }]
		      },
		 }
